Abstract: 221,478. British Thomson-Houston Co., Ltd., (Assignees of Classen, R.). Sept. 7, 1923, [Convention date]. Automatic circuit-breakers.-A switch or other device 4 is closed by the simultaneous energization of solenoids having plungers 18 which respectively engage the interconnected levers 22, 23 forcing them and the actuating bar 8 into the position shown in the Figure; the switch is tripped to open by a single tripping mechanism operated by an auxiliary solenoid. The pivot connecting the levers 22, 23 is held in its upper position against spring action by two toggles 28, 29 and 34, 35. The link 34 has an extension 36, Fig. 4, which bears against a catch 37 and so prevents the toggle 34, 35 from collapsing. The catch 37 is pivoted at 38 to a member 39 which can also pivot slightly against the action of a spring 41. The catch 37 is also held fast against a stop and prevented from counter-clockwise rotation by a member 42 which engages its lower end. Energization of the auxiliary solenoid raises a plunger 43 which knocks the member 42 away from the catch 37, allowing the catch to rotate and the member 36 to move upward, collapsing the toggles. Each plunger 18 may be actuated by two solenoids acting in tandem as shown. The switch may be closed by a handle 25 instead of by the solenoids. Specification 4663/14 is referred to.

Title: Improvements in musical instruments provided with a pitch indicator
IPC: G10D13/04
Filed: 1928-05-01
Abstract: 291,050. Mirfield, T. N. May 25, 1927, [Convention date]. Acoustic and vibration frequency speed indicators.-To facilitate tuning, the pitch of a drum, double-bass, 'cello, &c., is indicated by communicating forced vibrations from the instrument to a set of tuned reeds, that reed vibrating with the greatest amplitude which corresponds to the note of the instrument. The vibrations may be communicated mechanically, electromagnetically, or by a diaphragm receiving the air-vibrations. The vibration of the reeds may be shown by reflected beams of light. In the drum 12, the tuned metallic reeds 24 are mounted in open cells on a bar 22 rocking on springs 21, the bar 22 also carrying an arm 26 with pad 27 which transmits the vibrations of the drum-head 13. The reeds carry mirrors and reflect beams of light from a lamp 32, to adjustable mirrors 34 and thence to the translucent head 13 on which a scale is painted. The device is put out of action by a crank-handle 61, which controls the lamp, and also, by a cam 51 and arm 53, permits a spring 46 to lower an arm 42 pivoted at 40, a spring 56 being then permitted to raise an arm 55 pivoted at 41. The arms 42, 55 carry dampers 44, 59 which thus nip the reeds, and the arm 42 also depresses the arm 26 out of contact with the drum-head. In a modification the arm 26 contacts with the upper surface of the drum-heads and the reeds are observed directly. The reeds may be tuned to harmonics or other compounds, instead of to fundamental notes.
